LOCK COMBINATOR.

VApplication led May 9, 1923K.` Serial No. 637,721.

My invention lrelates to .improvementshln lock combinators and theobject kof my 1n- Y vention is to provide mechanical means for changingthe combination of a pm tumbler lock. A more specific object is toprovide mechanical means -for determining the combination of apintumbler lock to correspond to one or more keys that may be insertedvin the machine and for filling said lock to it said keys. f f

Other and more specific objects will be apparent from the followingdescription taken in connection'with the accompanying drawings. Inaccomplishing the above objects my device performs the following majorfunctions:

1. Ejection of oldy pins froml the lock mechanism. 1

2. Making new pins to match a certain key ror keys. l

3. MakingOf tumbler springs. y

4. Delivery of said springs and pins to the lock mechanism. l y

.5. Securing of same in place in the lock mechanism.

In accomplishing the aforesaid and other objects of my invention, I haveprovided means7 the preferred forms of which are 1l.
